Shower drain system and receiving element for a shower drain system

ABSTRACT

A drain system and receiving element for a drain system. The drain system is equipped with a drain arrangement, having a receiving element, which accommodates the drain arrangement in a covering manner and which is equipped with at least one holding element on which a veneer element can be reversibly fixed so that it can be removed. The receiving element for a drain system includes a receiving element that is designed as a separate, box-like hollow body that is constructed as a prototype box of a wall.

The invention relates to a drain system which is equipped with a drain arrangement. The invention relates also to a reception element for such a drain element.

DE 20 2008 003 050 U1 discloses shower drain arrangement, which forms a drain section for removal of water from the shower area and which contains an end section. The shower drain is equipped with a receiving section arranged so that it is laterally adjacent to the drain section, into which a shower plate is inserted with its end section.

DE 10 2007 043 327 A1 discloses a drain system which can be at least partially accommodated in the floor of a room. The drain system contains at least one structural part having a first section, which is extended along one wall of the room and on which can be installed for example wall tiles. The system further also includes draining means for the drain system, which can be partially installed in the floor of a room and which can be connected with a discharge pipe, wherein the drain system further contains at least one inlet opening, into which the waste water can enter so that the water which has entered the inlet opening can be delivered to the draining means. The draining means and/or the inlet opening are at least acoustically separated from at least one structural part.

Also known are shower elements at the floor level which are equipped at one front side or in one front side region with a draining arrangement that is used to carry away the shower water that falls onto the floor. The draining arrangement is usually equipped with an outlet drain, which collects the shower water and guides it through a siphon connected therebetween to an outlet pipe. In addition, the plate element can be deployed inclined in the direction supporting the draining arrangement, whereby the inclination can be used directly in the plate element, or created indirectly and so that it can be adjusted with supporting elements.

It is known that the advantage of walk-in showers is that they are barrier-free and easily accessible as they do not have stops. Moreover, the shower areas can deviate from standard measurements, in particular for shower tubs, as they can be individually adjusted to the installation conditions. Nevertheless, a problem that is often encountered here is that the positioning of the siphon or of the outlet pipe and its relationship to the arrangement of the outlet or to the outlet drain is acoustically connected also with the wall created in this manner. This creates a significant noise potential which must be perceived as very annoying under these circumstances.

The problem of the noise created in this manner should be solved by DE 10 2007 043 327 A1, wherein the outlet drain is coupled to acoustic damping elements of the wall.

However, this means that an extremely complicated construction is required along with other expensive measures.

A disadvantage is in this case that the drain arrangement is deployed in or on the plate element, and in particular that the shower drain or canal has relatively narrow dimensions, which means that the cleaning is complicated and labor-intensive. In spite of that, because the canal is wide, it must be provided with a drain cover to prevent an injury as the canal is arranged in the visible shower area and thus within a short distance so that the drain can be reached by the user.

The task of the invention is therefore to improve a drain system of the type mentioned in the introduction with simple means so that the draining arrangement can be freely positioned and is easily accessible, whereby the draining or discharging arrangement provides at the same time improved protection from noise while remaining almost invisible.

In accordance with the invention, the task is achieved when a receiving element accommodates a covered draining arrangement, wherein the receiving element is equipped with at least one holding element to which a veneer element can be detachably attached.

It is advantageous when a drain system is provided in this manner which has its discharging arrangement deployed inside the receiving element in the assembled state, whereby the discharging arrangement has no acoustically coupled contact to a wall as the discharging arrangement is arranged at a distance to the wall. The receiving element can be formed from a complying material. In a preferred embodiment, the receiving element can be manufactured from a preferred material which absorbs sound.

Suitable materials for the receiving element are coated or uncoated plates made of hard plastic foam using polyurethane or polystyrene as raw material. Other foam materials can be also used. Receiving elements from metal, plastic materials or molded bodies are also conceivable, without limiting the materials that can be used here in any way. Also conceivable are receiving elements consisting of construction panels which can be provided with suitable coatings on the surface. Essentially, materials which remain resistant to moisture during a long-term application can be taken into consideration as materials for the manufacturing of the receiving element.

In accordance with the invention, it is also particularly suitable when the discharging arrangement, in particular the siphon, can be arranged in variable locations within the receiving element. In addition, since the discharging arrangement is deployed inside the receiving element, it is therefore almost invisible or arranged so that it is covered. A separate cover is thus no longer required for the discharging drain since there is no longer any danger of an accident as the discharging arrangement is located outside of the contact area as if it were arranged outside of the actual shower area.

It goes without saying that the examples of applications for a shower region should not be seen as limiting.

What is important is that a variable wall integration element is provided, with which any horizontally acting drain type can covered or concealed while being integrated in a wall surface or in front of a wall surface. It is also conceivable that the drain system would be employed with washing tables on the bottom of a swimming pool, or in wellness facilities or even in public restroom. As long as this is a receiving element or a wall integration element which can be described as drain integration element, it may also be used separated from panel elements or existing floor superstructures can be also used separately.

In accordance with the invention, it is also advantageous when the receiving element is designed as a separate, box-shaped hollow body which is constructed as a front part of a wall. The receiving element can thus be set in advance in front of a wall, wherein the discharging arrangement can then be inserted in the assembled status into the cavity of the receiving element so that it is inserted therein.

In a simple embodiment, the receiving element is provided with such dimensions that a cavity is built which is seen as having a longer length than width in the axial direction. The length of the reception element or of the cavity in accordance with the invention runs parallel to the wall, while the width is to be considered as being oriented at right angle away from the wall.

The length of the reception element can be in a preferred embodiment adjusted to the longitudinal extent of the discharging arrangement or of the drain arrangement, but it can be naturally also designed longer than that. If the reception element is associated with a plate element or with a walk in shower, it is advantageous when in accordance with the invention, the receiving element is equipped at least with one axial length which corresponds to the length of the corresponding front side. Naturally, the positioning of the (wall) drain integration element is not limited to the longitudinal or cross-sectional design or dimensions. It is also conceivable for example when a diagonal)(45° path or an angled solution is provided for the discharging arrangement. It is also possible to create a rounded path for the discharging or for the drain arrangement when observed as a top view. It is advantageous when the receiving element or the (wall) drain integration element is manufactured so that it can be adjusted to the actual path of the drain arrangement, but also so that it can be separated from it.

The extent of the height of the receiving element or of the cavity can be also made variable so that it can be adjusted to the actual conditions available for the integration, but also according to the desires of the future customer. For example, the receiving element can be extended for instance over the entire height of the shower area, but it can be also designed so that it is much smaller so that the reception element is designed as a platform to make it possible to provide a surface to put away or make available shower utensils or the like. It is also conceivable that a base wall is provided with a front part of wall, which will be further explained later. Sanitary accessories can be naturally provided also on the receiving element and/or on the prototype wall or on the side which is oriented toward the shower area, which is true also about the intended applications above.

To make it possible to assemble the drain system, in particular the discharging or draining arrangement within the receiving element or within the cavity of the receiving element, it is very advantageous when in accordance with the invention, a corresponding region of the front side is provided with a corresponding opening for example in the shower area, so that an open and accessible front side is formed in which the drain arrangement can be integrated. This can be achieved when the drain arrangement is assembled in advance, for example on a plate element, or when the plate element is integrated in the corresponding drain area on the front side so that the plate element can be assembled with the drain in the area of the front side and the associated drain arrangement can be assembled in the cavity.

It is also advantageous when the receiving element is designed L-shaped so that it has a dorsal beam and a crossbar extended at right angle away from it, whereby the dorsal beam is in the assembled state arranged so that it runs parallel to one wall, while the crossbar is arranged on the upper side. The receiving element can be also mounted on the side of the base with a rising dorsal beam, for example on an existing floor coating or floor finish, wherein the crossbar is then oriented at right angle away from it and/or overlaps the path on the front side of the path of the plate element. It is preferred when the dorsal beam is mounted for example on the front side region of the plate element so that the receiving element will be overlapping the dorsal beam.

In another preferred embodiment, extensions are arranged on both sides of the receiving elements so that the receiving element appears in top view to have an almost C-shaped design.

It is possible to attach a corresponding structural element on one upper side of the crossbeam directly adjacent to the rising wall for the accommodation of a wall cover, or to attach the wall cover directly to the wall. The upper sides of the crossbeam could be also covered with a suitable cover such as for example tiles, so that for example a platform is formed in a preferred embodiment. However, it is also conceivable that a support system can be arranged on the upper side on the crossbeam which is correspondingly adjusted according to the amount of the transverse extension, so that a free front side of the crossbeam is terminated flush with a prototype wall arranged on the support system, and so that the surface formed in this manner can be also coated with a corresponding wall cover, whereby reinforcement and/or the like can be affixed to the newly formed wall as was already mentioned. Between the structural element and the wall formed in this manner is created a cavity, in which can be arranged corresponding damping elements and supply line or the like, which can be deployed between the wall and the prototype wall. The support system can be naturally also mounted on the extensions and/or directly on the dorsal beam, so that a crossbeam can then be eliminated.

Once the above mentioned components mentioned as examples, i.e. plate elements, drain arrangement and receiving element, have been assembled and mounted, the contact front side or the contact opening formed in the drain arrangement on the contact front side or between the optional cross beam and the plate element can be closed off with a suitable veneer element.

The veneer element is in this case naturally provided with such a height extension so that it is deployed at a distance, for example from the front side of plate element or a floor covering arranged on it, and so that a water passage gap is formed so that the water can be ordinarily removed for example from the shower area. A water passage gap is naturally provided also for other application purposes mentioned above. The veneer element can be naturally also arranged so that (for example) its free upper side which is deployed flush with the shower area is closed off with the optional crossbeam closes or with the upper surface of the prototype wall to make it possible to attach a suitable planned covering to the upper side. Between the covering arranged on the veneer element and the covering of the prototype wall can be also provided an impact seal having a sealing joint.

In a preferred embodiment, the veneer element is designed as a fine steel veneer which can be in another preferred embodiment deployed continuously at least on the upper side in the shower area.

It is advantageous when in accordance with the invention, the veneer element is arranged as an element which can be attached to and detached from the receiving element.

At least one holding element is provided when this is required for this purpose.

The invention thus provides a solution for the task defined above wherein a receiving element is provided in which a drain system is arranged in the assembled state and whereby the receiving element is equipped with an access opening, which can be reversibly closed with a veneer element, while the veneer element can be reversibly attached to a holding element arranged in the receiving element.

In an advantageous embodiment, the holding element is provided with a fixing rod which has a one fixing end, whereby a holding device is arranged on the fixing rod which can be adjusted relative to the fixing rod.

In order to attach the fixing element to the receiving element, it is advantageous when the holding element is equipped with thread on its fixing end. The thread is preferably designed as an external thread and it can be connected with an internal thread which has a corresponding design and which is arranged in a suitable position on the holding element. The holding element can be either screwed onto the crossbeam of the receiving element, or to a suitable device arranged opposite to the holding element. The important fact, however, is that the holding element can be mounted subsequently so that it does not interfere with the free front side opposite its fixing end, or with the actual fixing end, with the drain arrangement, while a variable positioning of the drain arrangement can be achieved, in particular of the siphon. In the case of the arrangement examples mentioned above, the holding element is extend with

its fixing end almost parallel to the dorsal beam and thus at right angle to the crossbeam of the receiving element.

However, it is also conceivable to connect the holding element with its fixing end to the dorsal beam so that the holding element runs with its fixing rod parallel to the crossbeam and it is thus arranged at right angle to the base element inside the cavity of the base element.

Depending on the installation position selected for the holding element relative to the dorsal beam, it is advantageous when a lateral holding device is arranged which is adjustable relative to the holding element, while it is naturally also possible to use a holding device which is adjustable relative to the holding rod opposite the fixing end of the fixing rod. In this preferred embodiment, the holding device then could be arranged at the free side of the fixing rod opposite the fixing end.

In a preferred embodiment, the adjustable holding device is provided with a magnet element having a holding element provided with an adjusting element arranged opposite to the holding element, which can be connected with a corresponding opposite adjusting element on the fixing rod. The adjusting element of the holding device can be referred to as a threaded rod, which can be screwed into a correspondingly designed tapped hole. The tapped hole can then be deployed in an embodiment on one of the longer sides of the fixing rod so that the holding device can be laterally adjusted relative to the fixing rod. The tapped hole can be arranged on the other side, but it can be also arranged at the free front side of the fixing rod so that the holding device is then arranged opposite the fixing end of the fixing rod.

It is essential that the holding device be adjustable relative to the fixing rod to make it possible to provide allowable variations for the installation or to provide compensation for the veneer element, since the surface of this veneer element is naturally flush in the preferred embodiment with the free front edge of the crossbeam which serves to close off the receiving element.

It is advantageous for the design of the holding element when the holding device is equipped with a magnet so that the veneer element can be reversibly detached from or connected with the receiving element, or so that the veneer element covers the access opening while being reversibly detachable.

This is in particular advantageous as the drain system must be from time to time cleaned, since the veneer element can then be easily removed based on the magnetic mounting support, while it cannot be removed unintentionally so that the access opening is then freed. The size of the access opening is selected to ensure that the entire drain arrangement, and in particular the discharging drain, is easily accessible and can thus be cleaned without complications. The access to the siphon, which must be also cleaned and eventually removed, is also without complications according to the invention.

Other advantageous embodiments of the invention are described in the subordinated claims and disclosed in the description of figures below. The figures show the following:

FIG. 1 a cross-sectional view of one example of a shower drain system,

FIG. 2 an enlarged section of FIG. 1 showing an example of a shower drain system,

FIG. 3 a top view of an example of a shower area having a drain system arranged in a receiving element,

FIG. 4 a view of a wall indicating the installation situation according to FIG. 1,

FIG. 5 through FIG. 7 an example of a holding element showing different embodiments and installation situations.

The same parts are always labeled with the same reference symbols in the various figures and as a rule described only once.

The FIGS. 1 through 3 show a drain system 1, for example a shower drain system 1, which is equipped with a drain arrangement 2 and a plate element 3. The drain arrangement 2 is arranged on a front draining region, or on a front drain side 4 of the plate element 3 in the embodiment indicated in the figure.

The drain arrangement 2 is connected with the plate element 3 and equipped with a discharge canal 6, with a siphon 5 that is connected with this discharge canal band with a discharge pipe which is connected with the siphon.

The drain system 1 with the drain arrangement 2 and the plate element 3 is suitable in a preferred application for walk-in installations, so that a barrier-free shower area can be created in a preferred embodiment. Onto the plate element 3 can be deposited on a free surface floor cover layers, in the present embodiment tiles, whereby a supporting footing can be arranged on the opposite bottom side. The plate element may also rest on its bottom side on a base. The plate element can be installed flush with the base for the finishing design, placed on floor cover layers such as wooden flooring boards, or it can be built into these elements.

Also conceivable are floor drain situation in which a conventional finishing design is produced in which a drain arrangement, namely a floor drain, is introduced, so that a plate element does not have to be used. It is also possible to mount the plate element 3 onto a superstructure, for example on a grid type of superstructure, which can be also integrated with the drain arrangement. Other embodiments relating to a plate element which is provided with a sealing element (for example a sealing foil, sealing fleece of fibrous web), or plate elements accommodating a drain are also possible.

An example of the shower region 7 of the drain system 1 is indicated in FIG. 3 as a top view. The plate element 3 is provided with an integrated inclination so that the shower water will be conducted in the direction of the drain arrangement 2, which is in FIG. 3 indicated by way of an example with the arrows 8.

It is advantageous when the drain arrangement 2 is arranged in a receiving element 9. The receiving element 9 is preferably designed as a separate, box-shaped hollow body which is formed as a prototype box for a wall 11 of the shower area. Although a shower drain system is described by way of an example, this example is in no way limiting. A possible drain arrangement 2 is generally provided with a receiving element 9 or with a (wall) drain integration element in a sanitary area, which can be employed as for example on a washstand, on the floor of a swimming pool, of a wellness facility or of public restroom facilities. The receiving element or the (wall) drain integration element can thus be installed separately from the plate elements or from the existing floor superstructures.

As one can see from FIG. 3, the receiving element 9 is equipped with a cavity 12 which is longer in the axial direction of the receiving element 9 relative to its width. The cavity 12 can be also referred to as a mounting space, wherein the drain front side area of the plate element 3 can be also installed in this mounting space 12. In this case, the plate element 3 is equipped in this integrated drain arrangement 2 with a discharge canal 6 so that the plate element 3 is in this area covered by the receiving element 9.

In this respect, the receiving element 9 is advantageously equipped with an open access front side 13 or with an access opening 13 into which the drain arrangement 2 can be inserted.

The receiving element 9 is provided with an L-shaped profile having a dorsal beam 14 and a crossbeam 16 extended at right angle to the dorsal beam, whereby the dorsal beam 14 is in the assembled state arranged so that it runs parallel to the wall 11. The crossbeam 16 is on the upper side arranged on the dorsal beam 14.

As one can clearly see from FIG. 2, the receiving element 9 is arranged upright with its base plate 18 on the free front side area 17 of the plate element 3 so that the first crossbeam 18 almost forms a lid for the cavity 12. The base side 18 can be naturally also arranged upright on a base floor, which is formed for example by the finishing design or by the concrete used in the room.

As can be also seen in FIG. 3, the dorsal beam is equipped on each of its opposite longitudinal sides with an extension 19 so that the dorsal beam almost forms a C-shape when seen from above. In the example of the embodiment which is shown in FIGS. 1 and 3, the dorsal beam 14 is extended between the opposite extensions 19, while it can be obviously also designed so that individually elements are linked with the dorsal beam 14 with a suitable connecting means, so that this dorsal beam can be also provided with joints in the axial direction.

As one can further also see from FIG. 3, the siphon 5 can be arranged for example in the center, whereby the respective adjacent and connected discharging canals 6 are designed with a corresponding inclination from outside in the direction to the siphon 5.

The receiving element 9, indicated by way of an example in FIGS. 1 through 4, is designed in a particularly preferred embodiment as a front part box which can be mounted in front of an erected wall 11.

It is evident that with this advantageous design, the receiving element 9 is formed with an L-shaped profile of the cavity 12, or of the mounting space 12 in which the drain arrangement 2 can be thus arranged.

It is also evident from FIGS. 1 and 2 that a support system 21 is arranged on one upper side 20 of the receiving element 21 or of the crossbeam 16, to which can be attached a prototype wall 22. As one can see for example from FIG. 2, the prototype wall 22 is enclosed on the side in the shower area with a free front wall of 23 of the crossbeam 15. It is also possible not to use the crossbeam 16, whereby the support system 21 will be erected on the extensions 19 and/or on the dorsal beam 14.

Between the erected wall 11 and the prototype wall 22 is thus formed a cavity 24, in which can be accommodated for example supply lines before the prototype wall or prototype walls are connected with the supporting element 21 to create a hermetic seal for the cavity 24. The side of the prototype wall, which is used for the shower region, can be lined with a suitable wall lining, for example with tiles 26, while a prototype wall which is manufactured in this manner can be naturally also used for attachment of sanitary armatures, soap containers or the like.

If the plate element 3 is installed with an associated drain arrangement 2 in the cavity 12 or in the mounting space 12, the access front side 13, or the access opening 13, can be reversibly closed off with a veneer element 25.

The veneer element 25 can be designed for example as a fine steel veneer, or it can be provided with tiles on the side which is turned toward the shower area in a preferred embodiment. It goes without saying that a shock absorbing element 38 having a sealing tape can be also provided between the coating on the veneer element 25 and the coating on the prototype wall 22 on which tile layer is deployed overhanging in the direction towards the free front side 23.

So that the blending element 25 can be connected with the receiving element 9 in a reversible manner, it is advantageous when in accordance with the invention, the holding element 27 is inserted for this purpose, which is arranged inside the cavity 12 or inside the mounting space 21 of the receiving element 9. The design of the holding element 27 will be explained in more detail later. It is advantageous when the holding element 27 is installed subsequently so that it can be removed.

The veneer element 25 is provided with such dimensions so that it can cover at least both opposite extensions 19 of the receiving element 9 and the entire access front side 13. By way of an example only, the receiving element has a height of 120 mm, wherein the cavity 12, or the mounting space has a width of 55 mm. The plate element 3 has for example a thickness of 30 mm, while the blending element can be provided with a thickness of 10 mm. The dimensions listed above are used only by way of an example and they should not be considered as limiting by any means.

As one can see clearly from FIG. 2, the veneer element 25 is arranged in such a way that it closes off with the free front side 23 the side which is oriented toward the shower area flush with the crossbeam 16. However, the veneer element 25 can be of course also arranged outside of the cavity 12 or outside of the mounting space 12, and it can eventually also partially or fully cover a the area of the free front side 23 of the crossbeam 16.

A similar design could be advantageous when the prototype wall 22 mentioned above is attached directly to the wall 11, so that one upper side of the crossbeam 16 can then be also covered with a coating and so that a sort of a platform is formed in this manner.

Due to the section which was selected for illustration purposes in FIGS. 1 and 2, only 1 holding element can be seen in the figures, while it was possible to indicate two holding elements 27 in the example which is shown in FIG. 4. More than two holding elements 27 can be naturally also provided, depending on the size of the access opening 13.

The holding element 27 is equipped with a fixing rod 28 and with a holding device 29 indicated on the free front side 32 arranged on the opposite side.

The holding element 27 or the fixing rod 28 is connected with the receiving element with the fixing end 31. This can be done on the crossbeam and/or on the dorsal beam.

According to a preferred embodiment, the fixing element 31 of the fixing rod 28 is provided with an external thread which can be screwed into a correspondingly designed sleeve having an internal thread, located either in the dorsal beam 14 or in the crossbeam 16.

The various attachments and arrangements of the holding elements are illustrated in FIG. 5 through 7.

The holding device 29 of the holding element 27 is in a technically advantageous manner designed as a magnetic element or a magnetic disk, which is equipped with a holding side 33 and a fixing side 34 deployed opposite the holding side. On the fixing side 34 is arranged an adjustment element 36 which can be connected with a counter-adjustment element located on the corresponding fixing element 28. The adjustment element 36, which can be also referred to as a grub screw, is inserted into a correspondingly designed threaded bore, created as a counter-adjustment element on one side of the fixing rode 28.

The fixing rod 29 has a square profile, wherein the fixing end 31 is in a preferred embodiment designed so that the fixing end 31 can be screwed into a corresponding inner thread sleeve. It is also conceivable that a sufficiently stable plug connection can be created, so that the threaded design then does not need to be used.

In the example which is indicated in FIG. 5, the holding element 27 is connected with its fixing rod 28 with the crossbeam 16, so that the fixing rod 28 is arranged so that it runs parallel to the dorsal beam 14. The holding device 29 is arranged on the side of the holing element 27 which is facing the region area so that the veneer element 25 is held by the magnetic force of the holding element 27.

Since a fine veneer which is not magnetically attracted is preferred for the design of the veneer element 25, corresponding magnetically active extensions are naturally provided in the corresponding holding region, so that magnetic holding force can be employed. Fine magnetic steels can be naturally also used. It is also possible to use a suitable magnetic material instead of the fined steel veneer, wherein it is further also possible to arrange in the material which is used for the veneer element 25 of the holding device 29 corresponding magnets or ferromagnetic inserts.

The holding device 29 is adjustable relative to the fixing element 28 to enable interaction of the adjusting element 36 with the counter-installation element arranged on the fixing rod 28. This is indicated by the rotation arrow 37 shown in FIG. 5. In addition, the fixing rod 28 is connected with its fixing end 31 to the crossbeam 16 in such a way so that free front side 32 of the fixing rod 28, which is opposite to the fixing end 31, is located at a distance from the discharge canal 6.

This is essential for the invention because the holding element 27 thus has no contact with the drain arrangement 2 or with the discharge canal 6. However, since it is preferred when the holding element is installed subsequently, the siphon should be arranged so that it can be freely positioned in the desired location to ensure better self-cleaning performance of the discharge drain.

The inclination of the discharge canal 6 to a given position of the siphon is naturally also adjusted.

The cooperation of the adjustment element 36 with the counter-adjustment element is also used so that the veneer element 25 can be positioned in order to close off with the free front edge 23 of the crossbeam 16 which is flush with the upper side in the shower region, or with the corresponding surface of the prototype wall 22. A similar type of fine adjustment can be easily achieved by turning the adjustment element 36 or the fixing rod 28 in the inward or outward direction.

It is further also clear from the figures that the veneer element 25 is deployed at a distance to the plate element 3, which is arranged at the lower front side opposite the crossbeam 16 or to the discharge canal 6 in such a way that an inlet gap 35 is formed for the shower water. The principle of this arrangement is shown in FIGS. 5 through 7.

As shown in the embodiment which is indicated in FIG. 6, the holding element is arranged in comparison to the embodiment indicated in FIG. 5 in such a way that a free front side 32, which is arranged there for the fixing end 31 of the fixing rod 28, is located at a distance from the crossbeam 16.

The fixing end 31 is in this case screwed or received in a suitable holding device, whereby a threaded design can be also used here to create engagement between the components. The important thing is that also with this arrangement of the holding element 27, the siphon can be mounted in a position which can be freely selected.

As shown in the embodiment which is illustrated by FIG. 7, the figure indicates another fixing variant of the holding element 27 on the receiving element 9.

In this embodiment, the fixing end 31 is connected with the dorsal beam so that the free front side 32 on the opposite side is oriented toward the shower area or toward the veneer element 25.

In contrast to the embodiments described above, the holding device is on the free front side 32 adjustably connected with the counter-adjustment element through the interaction with the adjustment element 36.

It is obvious that the holding element 27 can be positioned according to any of the embodiments shown in FIGS. 5 through 7, wherein any combination is naturally possible. For example, one holding element 27 according to FIG. 7 can be installed together with another holding element according to FIG. 5 and/or FIG. 7 to mention only one of many possible combinations.

The invention makes it possible to provide a (wall) drain integration element, wherein the drain system 1 is in particular acoustically decoupled with its drain arrangement 2 from a wall and rendered visually invisible, because the drain arrangement 2 is integrated in the receiving element which is also covered by the veneer element 25. The receiving element 9 is preferably dimensioned in such a way that that a sufficiently large revision opening is formed to make it possible for example to clean the discharge canal 6 and/or the siphon, or to perform maintenance of these components. It goes without saying that it is also possible not to employ the veneer element 25, which would however mean that the mounting space 12 would remain visible.

A particularly advantageous design and arrangement of the holding element 27 is to be seen in a design and arrangement in which this element is in the actual realization arranged so that the position of the siphon can be freely selected within the mounting space 12. The holding elements 27 are removable, which is a feature that can be used should these element interfere with cleaning or maintenance of the drain arrangement 2. Another essential feature is that the veneer element 25 is reversibly attached to the receiving element 9 so that a sufficiently large revision opening can be obtained should this be required.

As one can further also see from FIGS. 2 and 4, a continuous tile surface can be produced, which will cover, respectively, the side of the prototype wall facing the shower area, the free front side 23 of the crossbeam 16, but also the side of the veneer element 25 that is facing the shower area. Since the veneer element 25 can be removed along with the wall lining which is arranged on it, it is advantageous when a shock damping seal is created with a sealing tape 38 which is provided between the wall lining of the veneer element and the wall lining of the prototype wall.

It is finally also possible to provide a dry construction laterally to the correspondingly adjusted receiving element 9 with a corresponding cavity 41 for the wall 11, which can be seen for example in FIG. 3. Damping elements 42 can be arranged in the cavities 24 (FIGS. 2) and 41 (FIG. 3), which also provide support for the prototype wall 22.
